In some embodiments, the vent may have a shape that imparts information to a view of the bill of the cap.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 63/148,301, entitled “CAP HAVING A VENTED BILL,” which was filed on Feb. 11, 2021, and the entirety of which is incorporated herein by reference.

BACKGROUND

Caps, commonly referred to as “baseball caps,” are a form of headgear worn during some sporting activities (e.g., a baseball game) and, more frequently, as casual attire. A typical cap includes a head cover designed to fit over the wearer's head and a bill that extends away from the head cover. The bill is generally designed to provide an amount of shade and/or coverage for the wearer's eyes from the sun or other light source when the cap is worn in the forward orientation (i.e., with the bill facing forward). However, in other situations, the wearer may don the cap in a backward orientation (i.e., with the bill facing backward), such as when the sun or light is not a concern to the wearer and/or as part of the wearer's fashion.

Although the bill is designed to provide the wearer with some utility, including protection from the sun, the bill can also cause difficulties for the wearer in some circumstances. In particular, the bill may have the tendency to cause the cap to dislodge from the wearer's head during some activities or time periods, such as those in which a high velocity airflow is directed toward the bill. In such situations, the high velocity airflow can cause the bill to act as a “sail” and pull the cap off the wearer's head, regardless of whether the cap is worn in the forward or backward orientation. For example, caps are often worn by operators of motorcycles. However, while riding a motorcycle, airflow may be directed toward the bill at enough velocity to cause the bill to lift up and resultantly pull the cap off the operator's head.

SUMMARY

According to an aspect of the present disclosure, a cap may include a head cover, a bill, and a mesh. The head cover may be configured to be worn on the head of a user of the cap. The bill may extends from the head cover and may include an inner wall that defines a vent through the bill. The mesh may be located in the vent and may be configured to allow an amount of airflow through the vent while the cap is worn by the user.

In some embodiments, the mesh may be embodied as a fabric mesh. Alternatively, in other embodiments, the mesh may be embodied as a rigid structure. In such embodiments, the rigid structure may include a rigid frame formed from a plastic material.

In some embodiments, the bill may include a top substrate and a bottom substrate. In such embodiments, a first inner wall of the top substrate and a second inner wall of the bottom substrate may cooperate to define the vent. Additionally, a periphery of the mesh may be positioned between the top substrate and the bottom substrate such that the mesh extends across the vent. Additionally, the mesh may be positioned centrally within the vent when the bill is viewed from a plane perpendicular to the vent and extending through the vent.

Additionally, in some embodiments, the cap may further include a bill covering. The bill covering may include a top cover that wraps around the first inner wall of the top substrate and a bottom cover that wraps around the second inner wall of the bottom substrate. Additionally or alternatively, the mesh may be secured to a bottom side of the bill. In such embodiments, the bill may include a substrate, and the mesh may be sewn to a bottom side of the substrate.

In some embodiments, the cap may also include a detached indicia structure secured to the mesh and spaced apart from the bill. The detached indicia structure may be secured to a top side of the mesh. In some embodiments, the detached indicia structure may be embodied as a top indicia structure secured to a top side of the mesh and a bottom indicia structure secured to a bottom side of the mesh such that a portion of the mesh is located between the top indicia structure and the bottom indicia structure. Additionally, in some embodiments, the top indicia structure and the bottom indicia structure have an identical shape. Furthermore, in some embodiments, the detached indicia structure may be formed to have a shape that provides information to a viewer of the bill of the cap when the bill is viewed from a top side of the bill.

Additionally, in some embodiments, the vent may have a shape that provides information to a viewer of the bill of the cap when the bill is viewed from a top side of the bill. For example, the vent may have an alphanumerical shape when viewed from the top side of the bill. Additionally or alternatively, the vent may be shaped as a logo or emoji. In some embodiments, the logo or emoji may be associated with an entity identified on the head cover of the cap.

According to another aspect of the present disclosure, a cap may include a head cover and a bill. The head cover may be configured to be worn on the head of a user of the cap. The bill may extend from the head cover and may include an inner wall that defines a vent through the bill. The shape of the vent, when viewed from a top side of the bill by a viewer, provides information to the viewer.

In some embodiments, the bill may include a substrate, a bill top covering attached to a top side of the substrate, and a bill bottom covering attached to a bottom side of the substrate. In such embodiments, the substrate may include the inner wall. The bill top covering and the bill bottom covering may be sewn to each other along the inner wall.

Additionally, in some embodiments, the bill may include a substrate and a bill covering attached to a top side of the substrate. In such embodiments, the substrate may include the inner wall, and the bill covering may wrap across the inner wall from a top side of the substrate to a bottom side of the substrate and is sewn to the a bottom side of the substrate along a periphery of the vent.

In some embodiments, the vent may have an alphanumerical shape when viewed from the top side of the bill. For example, the vent may be shaped as a logo or an emoji. In some embodiments, the logo or emoji may be associated with an entity identified on the head cover of the cap.

Additionally, in some embodiments, the inner wall may be embodied as a first inner wall and the vent may be embodied as a first vent. In such embodiments, the bill may further include a second inner wall defining a second vent through the bill. Additionally, in such embodiments, the first vent may have a shape, when viewed from a top side of the bill, in the form of a first alphabetical character and the second vent may have a shape, when viewed from a top side of the bill, in the form of a second alphabetical character different from the first alphabetical character.

Similarly, items listed in the form of “at least one of A, B, or C” can mean (A); (B); (C); (A and B); (A and C); (B and C); or (A, B, and C).

In the drawings, some structural or method features may be shown in specific arrangements and/or orderings. However, it should be appreciated that such specific arrangements and/or orderings may not be required. Rather, in some embodiments, such features may be arranged in a different manner and/or order than shown in the illustrative figures. Additionally, the inclusion of a structural or method feature in a particular figure is not meant to imply that such feature is required in all embodiments and, in some embodiments, may not be included or may be combined with other features.

Referring now to FIGS. 1-3, a cap 100 is configured to be worn on the head of a wearer in the manner that typical “baseball caps” are worn (e.g., in a forward, side, or backward orientation). The illustrative cap 100 includes a head cover 102 and a bill 104. The head cover 102 is shaped and sized to be worn on the wearer's head. For example, in the illustrative embodiment, the head cover 102 has a generally hemispherical shape and includes a convex outer surface 110 and a concave inner surface 112 opposite the outer surface 110. As shown in FIG. 3, the concave inner surface 112 defines a cavity 114 that is configured to receive an upper portion of the wearer's head. Illustratively, the head cover 102 is made from a fabric material, but may be made from a rigid material (e.g., a plastic material) in other embodiments. To facilitate varying sizes of wearers' heads, the head cover 102 may include an adjustment mechanism such as an adjustment band having a number of preset adjustment locations or a “continuously” adjustable band. Regardless, the adjustment mechanism is operable to adjust the circumference of a lower band of the head cover to thereby adjust a diameter 116 of the cavity 114 to properly fit the wearer's head, similar to typical “baseball caps.”

As best shown in FIG. 1, the head cover 102 includes a front side 118, which faces the same direction as the bill 104. In some embodiments, indicia may be included on the front side 118 of the head cover 102. The indicia may be embodied as any type of textual and/or pictorial indicia that identifies an entity (e.g., the manufacture of the cap 100), identifies the wearer of the cap, embodies an advertisement, and/or otherwise provides information to a viewer of the cap 100 while the cap 100 is worn by the wearer.

The bill 104 is attached to (e.g., sewn to) and extends from the head cover 102. Similar to typical “baseball caps,” the bill 104 is configured to provide an amount of protection from sunlight and other light sources to the wearer while the cap 100 is worn in a forward direction (i.e., with the bill facing forward). However, unlike typical “baseball caps,” the bill 104 of the cap 100 includes an inner sidewall 120 that defines a vent 122 through the bill 104. The vent 122 is embodied as an open vent (e.g., allows unrestricted air flow there through) in the illustrative embodiment of FIGS. 1-4, but may be embodied as a meshed vent in other embodiments as discussed in more detail below.

It should be appreciated that typical bills of “baseball caps” are designed to be solid, without the inclusion of any vents or holes, so as to provide the above-discussed protection from sunlight. However, the inclusion of the vent 122 in the bill 104 increases the likelihood that the cap 100 remains on the wearer's head during certain activities that may tend to cause typical caps with solid bills to become dislodged from the wearer's head. In particular, the vent 122 increases the likelihood, relative to a solid bill, that the cap 100 remains on the wearer's head during activities in which airflow is directed toward the bill 104 at a high velocity (e.g., while motorcycling, boating, jet skinning, etc.). Rather, the vent 122 allows an amount of the airflow directed toward the bill 104 to pass through the vent 122 and, as such, reduces the “sail-like” impact of the bill 104 that causes dislodgement of typical “baseball caps.” As discussed in more detail below, the number, shape, and size of the vent 122 may be selected and/or designed based on a number of criteria including, for example, the expected activity to be performed while wearing the cap 100, the size of the cap 100, any information that may be desired to be provided by the shape of the vent, other information displayed on the cap (e.g., on the front side 118), and/or other criteria. Although most illustrative embodiments are shown and discussed below as having a single vent 122, it should be appreciated that the cap 100 may have multiple, separate vents in other embodiments.

Illustratively, the bill 104 includes a substrate 130, which may be formed from any suitable rigid material such as a cardboard, plastic, or metallic material. In this way, the substrate 130 provides an amount of rigidity and structure to the bill 104. However, in some embodiments, the substrate 130 may allow manipulation by the wearer to adjust or form the shape of the bill 104 (e.g., to establish a desired frontal curvature to the bill 104). It should be appreciated that the substrate 130 includes the vent 122, which may be established during manufacturing of the cap 100 by forming (e.g., cutting or punching) the vent 122 into the substrate 130. In such cases, the sidewall 120 that defines the vent 122 is embodied as an inner sidewall 120 of the substrate 130 as shown in the illustrative embodiment of FIGS. 1-4.

The bill 104 also includes a bill covering 132, which wraps around the substrate 130. The bill covering 132 may be made from any suitable material such as a fabric or plastic material. Illustratively, the bill covering 132 includes a top bill covering 134, which is attached to or otherwise covers a top side 144 of the substrate 130, and a bottom bill covering 136, which is attached to or otherwise covers a bottom side 146 of the substrate 130 as shown in FIG. 4. The top bill covering 134 and the bottom bill covering 136 may be formed from the same or from different material and may have the same color and/or overall look or may have a different color and/or overall look. For example, in some embodiments, the bottom bill covering 136 may be of a lighter color than the top bill covering 134. As such, the top and bottom bill coverings 134, 136 may be formed from separate pieces of material or from the same piece of material (e.g., a unliterary construction).

As shown in FIG. 4, in the illustrative embodiment, the top bill covering 132 and the bottom bill covering 134 are attached together along a seam 150 positioned on the inner sidewall 120. For example, the top and bottom bill coverings 134, 136 may be sewn or glued to each other along the seam 150. Because the seam 150 is located along the inner sidewall 120, the seam is less visible when the bill 104 is viewed from the top side or bottom side. In this way, the bill covering 132 may wrap around the inner sidewall 120 such that the inner sidewall 120 of the substrate 130 is not visible and the visibility of the seam 150 is also reduced.

Of course, in other embodiments, the top bill covering 132 and the bottom bill covering 134 may be attached together along a seam located away from the inner sidewall 120. For example, as shown in FIGS. 5 and 6, the top and bottom bill coverings 132, 134 may be attached together along a seam 550 defined along the perimeter of the vent 122 on the bottom side 146 of the substrate 130 of the bill 104. In such embodiments, the seam 550 is not visible from the top side of the bill 104 or through the vent. Rather, as shown in FIG. 6, the top bill covering 134 wraps completely across the inner sidewall 120 of the substrate 130. Of course, it should be appreciated that the location of the seam 150, 550 of the top and bottom bill coverings 132, 134 may be determined based on various criteria including, for example, the shape and size of the vent.

As discussed above, the vent 122 may have any suitable shape or size based on a various criteria. In some embodiments, the shape of the vent 122 is selected or otherwise defined so as to impart information to a viewer of the bill 104. For example, the vent 122 may be shaped in the form of a logo (e.g., a company or team logo), letter(s), number(s), word, phrase, emoji, emoticon, picture, alphanumerical representations, and/or other shape that imparts information to a viewer of the cap 100. For example, in the illustrative embodiment of FIG. 7, the vent 122 is shaped as two joined circles, similar to a venn diagram, which may embody a company or team logo or the like. Alternatively, in another illustrative embodiment shown in FIG. 8, the vent 122 is shaped as a “smiley face,” which may embodied an emoji that imparts the information that the wearer is in a happy mood. Of course, in other embodiments, the vent 122 may have other shapes and/or sizes. In some embodiments, the vent 122 has a shape associated with indicia included on the front side 118. For example, in an illustrative embodiment, an entity's name (e.g., a company name) may be included on the front side 118 and vent 122 may be shaped as the entity's logo (e.g., the company's logo).

Referring now to FIGS. 9-13, in other embodiments, the vent 122 may be embodied as a mesh vent 122. In such embodiments, the cap 100 includes a mesh 900 located in the vent 122. The mesh 900 is configured to allow an amount of airflow through the vent 122 while the cap 100 is worn by the wearer, while also providing some additional amount of protection from sunlight and/or other light sources to the wearer. As such, the mesh 900 may be made from any suitable mesh material such as a fabric mesh. Additionally, the mesh 900 may have any suitable color. For example, in some embodiments, the color of the mesh 900 may match the color of the top bill covering 134, the bottom bill covering 136, or be different from the color of the top and bottom bill coverings 134, 136.

In some embodiments, the mesh 900 is attached to the top side or the bottom side of the bill 104 and positioned so as to cover the vent 122. For example, the mesh 900 may be attached to the top side 144 of the substrate 130. In such embodiments, a periphery of the mesh 900 may be positioned between the top bill covering 134 and the top side 144 of the substrate 130 and sewn, along with the top bill covering 134, to the substrate 130. Alternatively, the mesh 900 may be attached to the bottom side 146 of the substrate 130. In such embodiments, a periphery of the mesh 900 may be positioned between the bottom bill covering 136 and the bottom side 146 of the substrate 130 and sewn, along with the bottom bill covering 136, to the substrate 130.

Alternatively, as shown in the illustrative embodiment of FIGS. 12 and 13, the mesh 900 may be positioned centrally within the vent 122 in the vertical direction. That is, as shown best in FIG. 12, the mesh 900 is located in the middle of the inner sidewall 120 when the vent is viewed from an imaginary plane that is perpendicular to the vent 122 and extends through the vent 122. In such embodiments, the substrate 130 may be formed from a top substrate 1200 and a bottom substrate 1202, which cooperate with each other to form the substrate 130. A periphery of the mesh 900 may be located or “sandwiched” between the top and bottom substrates 1200, 1202 such that the mesh 900 extends across the vent 122 in a vertically central location. In such embodiments, the inner sidewall 120 is formed from an inner sidewall 1210 of the top substrate 1200 and an inner sidewall 1212 of the bottom substrate 1202. In some embodiments, as shown in FIG. 13, the top bill covering 134 wraps around the inner sidewall 1210 of the top substrate 1200 and the bottom bill covering 136 wraps around the inner sidewall 1212 of the bottom substrate 1202 such that the periphery of the mesh 900 is captured between the top and bottom bill coverings 134, 136.

Referring now to FIGS. 14-17, in some embodiments, the cap 100 may further include a detached indicia structure 1400 secured to the mesh 900 but spaced apart from the bill 104. In this way, the indicia structure 1400 is detached from the bill 104 (e.g., from the substrate 130) and forms an “island” that is supported by the mesh 900. The detached indicia structure 1400 may have any suitable size and shape depending on various criteria. For example, in some embodiments, the size and shape of detached indicia structure 1400 is dependent on how much airflow is desired through the vent 122. The detached indicia structure 1400 may have a larger size to restrict the airflow or a smaller size to allow more airflow through the vent 122. In some embodiments, the detached indicia structure 1400 may form part of the overall information provided by the shape of the vent 122. For example, the detached indicia structure 1400 may form part of a logo, letter, or phrase formed by the vent 122. The detached indicia structure 1400 may be formed from any suitable material such as a rigid material. In the illustrative embodiment, the detached indicia structure 1400 is formed from the same material as the substrate 130 and may include its own covering, which may be similar to the bill covering 132. As such, the color of the detached indicia structure 1400 may match the color of the top bill covering 134, the bottom bill covering 136, or may have a different color.

As shown in FIG. 16, in the illustrative embodiment, the detached indicia structure 1400 is attached to a top side 902 of the mesh 900 in a location that is spaced apart from the substrate 130 of the bill 104. For example, the detached indicia structure 1400 may be sewn or glued to the mesh 900. Alternatively, in other embodiments as shown in FIG. 17, the detached indicia structure 1400 may be embodied as a top indicia structure 1700 and a bottom indicia structure 1702. In such embodiments, the top indicia structure 1700 is attached to a top side 902 of the mesh 900 and the bottom indicia structure 1702 is attached to a bottom side 904 of the mesh 900. To so, the top and bottom indicia structures 1702, 1704 may be sewn or glued to the mesh 900. In such embodiments, the top and bottom indicia structures 1702, 1704 may or may not have similar shapes, sizes, and/or colors.

Referring now to FIGS. 18 and 19, in some embodiments, the mesh 900 may be embodied as a rigid structure 1800. In such embodiments, the rigid structure 1800 is configured to allow an amount of airflow through the vent 122 while the cap 100 is worn by the wearer, while also providing some additional amount of protection from sunlight and/or other light sources to the wearer. The rigid structure 1800 may be made from any suitable rigid material such as a plastic or metal material. Additionally, the rigid structure 1800 may have any suitable color. For example, the color of the rigid structure 1800 may match the color of the top bill covering 134, the bottom bill covering 136, or be different from the color of the top and bottom bill coverings 134, 136. The rigid structure 1800 may be attached to the bill 104 in one of the manners described above in regard to the mesh 900.
